Alan,
I updated to these versions when they appeared previously and did not experience any problems during the upgrade process (I noted this in your original thread). Naturally they do not appear as an update option now. Should I be concerned? Thanks.

Include as much detail as possible: the exact error message, when it displayed, what version you were running before the update, did you see the message immediately after downloading the update, what version of Windows are you using, are you running with administrator privileges, etc.
